M3 trailing arm bushings
 

Please excuse the BMW content, but does anyone have experience with these?:

I believe these were the bushings I was told about by a trusted buddy, but while I wait for him to find my message, I thought I would try the Dorki collective.

Is it true that there is no downside to these bushings over the OEM except maybe cost? They are not prone to eating up the chassis like solid bushings do in other applications, right?

If you use the welded reinforced pieces you should be ok, the downside is driving this on the street, the ride will quite rough. try powerflex bushings

Is this from personal experience with this bushing in this location?

The ride would be very rough and loud on the street. There is nothing wrong with the stock bushings if the car is not tracked. The powerflex bushings will still transmit NVH into the cabin, but not as much. The M3 floor is already reinforced. In my experience the floor tearing in due to hard launches from a stop. You may want to reinforce the swaybar mounts.

This M3 gets plenty of track time. It has about 175 days on it so far ;o)

Could you imagine what was meant by "monoballs" or hiem joints for this part?

X2. I had some Turner stuff and some T.C. Klien stuff in my E36. After I got tired of rewelding the car due to metal fatigue, I replaced almost the entire car with the PowerFlex stuff. I recommend them, this is personal experience and the couple of cars I built for Malvern Racing.

X3 on Powerflex.

I have them for control arm bushings and rear sub-frame on my E30s and for thrust (lower control arm) and soon F control arm on my E39. I went with K-mac adjustable eccentric poly trailing arm bushings on the back of one of my E30s to get some camber back from the spring drop (different setup v. your E36).

They DO transmit some NVH but nowhere near as soft and as failure prone as the webbed E30 pieces and the fluid filled E39 peices (o crap -- IMNSHO).

I would think solids would be to much for the street on the BMWs.

Thanks to all the responders. Once I saw the Powerflex bushings were PURPLE I was sold.

They are on order.

Go Ravens!

Good decision.

FWIW they ship with a copper based antiseize "lubricant." It is the same stuff, I called bimmerworld and powerflex usa (same people) to confirm, as high temp copper based lubromoly antiseize. Afters crewing around with other stuff ... I lube them with lubromoly copper based antiseize ... haven't had to go back "in there" for years to relube and quiet squeaks.

YMMV and all that.

Ive always been told not to use Urethane in the RTAB. It doesnt allow for movement in all axes.
